Determinación y mapificación de la fertilidad mediante los sistemas de información geográfica sig del cantón Huaquillas provincia El Oro

Currently using Geographic Information Systems (GIS).GIS are increasingly used tools in the planning process. The formation of a geographic database of the different levels that are present in the essential elements to plants can help with planning, and better soil management. By processing and interpretation of test results could know the status of the soil with the help of the programs are unable to process so that they could be visual and more explanatory. (GIS). The objectives were: 1.Determinar fertility of soils by texture analysis, cation exchange apacity, electrical conductivity, organic matter, Na + Ca + +, Mg + +, K + exchangeable, H, N, P, K, Ca, S,and complementary B, Fe, Cu, Zn, Mn, Mo, 2. Recomendar, dosages technically suitable amendments, fertilization and abonadura to increase production of major crops for export and domestic consumption of the canton Huaquillas, 3. to map the texture, cation exchange capacity, electrical conductivity, fertility, pH, organic matter, and exchangeable bases in Canton Huaquillas The research was performed in theSoil laboratory of the Faculty of aguicultural Sciences at the Technical University of Machala, parish Change, Canton Machala, El Oro Province, Region 7.Huaquillas Canton is located in thesouthwestern part of the Province of ElOro has 66.14 km2, is located at a height of 12 msnm bounded on the north and east by the canton Arenillas, south to the Republic of Peru to the west thear chipelago Jambelí. Theprotocols for soil analysis were: for organic matter, Walkley and Black, for themechanicalanalysis, Bouyucus forthe cationexchangeapacity,Formaldehyde,forelectricalconductivity,Conductometers thegrassroots exchangeable Na+, Ca++, Mg++, K+, the acro-and micronutrients, N, P, K, Ca, S, B, Fe, Cu, Zn, Mn, atomic absorption spectrophotometer, and pH, Conductometers. For the calculations offertilization was consideredas representative crop hard corn. There sults obtained allowed the following conclusions: the source material which comprises the soil is within a range of minerals. The bedrock that gave rise to soils is sedimentary detritus. The source material of the soil and climatic factors influenced the presence ofsand, silt and clay textural classes. Most soils tended to neutrality and basicity. The organic matter was low in the canton. In nitrogendominates the very low level. The macro and micronutrients ha danirregular distribution and varying concentrations. The cation exchange capacity increasesin areas where there arepredo minantly silt and clay. The maps obtained were: texture, cation exchange capacity, organic matter, Na+, Ca++, Mg++, K+, changeable, pH, N, P, K, S, Ca, Mg and complementary B, Fe, Cu, Zn, Mn, and , electrical conductivity.
